SPECIFICATION forming part of Letters Patent No. 414,530, dated November 5, 1889.

Application filed August 17, 1889. Serial No. 321,074. `(ll'o model.)

To @ZZ wwm t may concern;

Be it known that I, MAHLON HAMLIN, a citizen of the United States, and a resident of Catawissa, in the county of Columbia and State of Pennsylvania, have invented certain or dismantled in case of accident or for other.

reasons; secondly, in providing a construction whereby the employment of a linchpin is rendered entirely unnecessary, and, thirdly, in providing a construction whereby dirt and grit are effectually prevented from entering the box and `clogging and with these ends in view it consists in the improved construction and combination of parts, as hereinafter more fully set forth and described.

In the accompanying drawings, Figure l is a perspective View of a sectionof a car body or truck, showing my improved box and wheel applied thereto. Fig. 2 is a longitudinal vertical sectional view. Fig. 3 is a cross-sectional view on the line m, Fig. .2. Fig. i is a crosssectional View on the line y y, Fig. 2. Fig. 5 is an inverted plan view of the upper section or pedestal, and Fig. 6 is a plan view of the lower section or cap.

Referring to the drawings, in which like letters of reference refer to the like parts throughout the several figures, the letter A indicates the car body or truck. Secured beneath the car body or truck is the axle or tour, and is provided at one end with later` ally-extendin g ears c, between which the outwardly-extending lug b fits, said ears being Y provided with perforations or bolt-holes c c', which register with the perforations in the depending lug, and through which registering perforations a transverse bolt E passes, thereby assisting in securing the two sections of the box together. The opposite end of the cap C is provided with a curved and iianged portionortonguec2,whichtheinwardly-curved lug C is adapted to engage, and to facilitate the insertion of the lower cap-piece the sides of the outwardly-extending pieces D D', opposite to the inwardly-curved hooks, are likewise concaved or curved, thereby forming a recess into which the slightly-curved end and flange of the lower section is seated. The inner curved surface of the cap or lower section is formed near its outer edge with a semicircular groove or recess c3, while its inner edge is formed with a lower upwardlyextending segmental rim or iiange c4, the ends thereof forming a seat or support for the inner centrally-depending side piece D.

Then the upper and lower sections of the box are united, which is accomplished by inserting the curved end within the curved recess hereinbefore described, and also allowing the end lug of the upper section to pass between the laterally-extending perforated lugs or ears of the lower section, and securing the same by means of the bolt, it will be seen that a complete circular opening is formed, the outer opening, however, being greater in circumference than the inner, and

with an annular recess formed tothe rear thereof, while the inner or contracted circular opening has formed to the rear thereof a semicircular space or recess, the formation of which is due to the widened or thickened de pending central lug D.

The car-wheel is represented by the letter F, the hub G thereof extending inwardly and IOO 6o providing for the continuous lubrication of 65 found to iirmly uniteY the two sections.

providedwith an annular recess g, into which recess the curved edge of the centrally-depending piece D of the upper section, aswell as the outer wall of the groove c3 of the lower section or cap, fits loosely, so as to allow of a limited lateral play of the same therein, usually about one-fourth of an inch. This is particularly advantageous when diiferent widths or gages of trucks are encountered, permitting the wheels to accommodate themselves to varying widths without strain or liability of breakage. lf this slight lateral play was not allowed for, it will readily be seen that in turning curves, or, as stated,

when varying gages are encountered, damage would of necessity follow. It will be further seen that the circumference of the end collar -g of the annular recess g is somewhat less than the circumference described by the an- `,nular groove into which it lits, thereby pre- Yin the usual manner, completely filling up the circular inner opening of the hub of the wheel and the circular opening upon the inlnerside ofthe box, while to the rear of the segmental rim or iiange c4 of the lower section a segmental packing-chamber l is formed when the two sections are secured together, into which suitable packing may be disposed.

From the foregoing description the construction and advantages of my improvement ,will be readily understood. It will be seen that vthe'einployment. of a linchpin for securing the wheel to the axle is entirely obvi'ated. Further, the two sections of the journal-box may be readily detached with only the necessity'of removing a single bolt, which will be found particularly advantageous when for any reason access to the interior of the box .is 'made necessary. Further, by the constructio'nof the inwardly-,extending hub or nave .with an annular collar upon the extreme end thereof, fitting within the appropriate recesses, a construction is obtained which will preclude the possibility of entrance of dust at this point. Furthermore, by allowing a slight lateral play to the hub of the wheel Vthis will compensate for, as previously stated, varying widths or gages of tracks and facili- .tate the turning of sharp curves. It will further be observed that my improved axlebox and wheel may be used with equal ad- .vantage upon all other classes of cars and vehicles, but very little change in the construction now employed being necessary; also, the recess in which the annular collar of the hub turns forms a convenient oil-chamber, thus .this portion of the device;

The transverse bolt E, previouslydescribed, is by preference made split; or l employ what .is termed a double key, which will bel Y Having thus described my invention ,-I' claim depending pieces and a curved recess between and desire to secure by Letters Patentof the United States-- 'l 1.
